MEANS FOR DELIVERING. OIL AND OTHER LIQUIDS.

To all whom it may concern Be it known that 1, JAMES CALDWELL Srnnrox, a subject of the King of Great Britain and Ireland, residing at VJestminster, London, England, have invented Improvements in Means for Delivering Oil and other Liquids, of which the following is a specification.

This invention relates to apparatus for delivering oil or other liquids by steam pressure of the type in which the liquid is admitted to a chamber by gravity or by condensation of steam within the chamber and is expelled therefrom by steam pressure, the steam also serving to heat the liquid; and the invention has for its object to provide improved apparatus of this description, particularly suitable for use in connection with the carbureter or other chamber of gas manufacturing plant, possessing the advantages pertaining to the apparatus for this purpose described in specification of my British Letters Patent No. 25,385 of 1905, but of simpler and cheaper construction.

Apparatus of the type describedac'cording to the present invention comprises a single cylinder or chamber, (hereinafter referred to as a cylinder) the upper portion of which is adapted to receive charges of the liquid to be delivered, while its lower portion, consisting approximately of the lower half of the cylinder, is adapted to contain water due to the condensation of the steam, and to retain the same for a time sufficient to permit of the transfer of heat to the charge, thus considerably increasing the heating efficiency of the apparatus. The inlet and outlet for the liquid charge, the steam supply inlet, and the outlet for water of condensation are controlled by valves con nected to an operating rod, the arrangement being such that when, by means of this rod, the steam supply is cut oh and the liquid outlet closed, liquid will be caused to enter the cylinder, while when, by means of the rod, the liquid outlet is opened, the steam supply 'opened,and the liquid inlet closed, the liquid will be displaced from the cylinder by the direct action of the steam.

Figures 1 and 2 of the accompanying drawing illustrate in sectional elevation two forms of apparatus according to this invention.

In Fig. 1 B is the cylinder, D is a valved steam pressure connection into the top of the cylinder through a steam distributer Specification of Letters Patent.

U; H is the valved connection from the tank or reservoir not shown) from which the liquid is to be drawn, ending in a nozzle or sprayer V in the top of the cylinder; G is the valved discharge connection through which the liquid is to be delivered; W is a testpipe running down below the bottom of the discharge pipe as a means of ascertaining whether the water has risen to this level it the gage R, hereinafter referred to, is not in use; X is a valved air vent terminating below the level of the steam inlet, so as to control and maintain an air space in the upper portion of the cylinder; M is a valve outlet for the condensed water terminating at the outer end in a regulating cock Y which can be adjusted to allow the water to escape at any desired rate; R is a gage glassand cocks with scale which is slightly movable so that it can be adjusted to compensate for any dilference in the level of the condensed water at the beginning and end respectively of each discharge or run which may occur owing to the discharge of water through the outlet M being more or less than is condensed and collected at the bottom of the cylinder during the same period. The levers of the four cocks or valves on the connections M, D, G and H respectively are connected, according to one method, by an operating rod T as shown. so that M, D and G are open when H is shut. and vice versa. The cylinder being full of oil (except for the condensed water in the bottom) up to the end of the air vent X, which coincides with the zero of the movable scale in its central position, the connection H being open and the connections M, D and G shut, the rod T is moved over, shutting H and opening M, D and G. Steam under pressure then enters the top of the cylinder through the connection D, depressing the surface of the oil and discharging it through the connection G, while at the same time discharging the condensed water (which sinks below the oil) through the connection M, the regulating cock Y being set to keep the level of the water as nearly as possible constant. When the desired quantity of oil has been delivered, as indicated upon the gage and scale (the latter having been so adjusted that the water level is opposite the same point on the scale as it was at the beginning of the discharge) the rod and cooks are reversed, M, D and G being shut off and H opened. The steam then in the upper portion of the cylinder is condensed by the incoming oil or other liquid, which automatically fills the cylinder to the zero level ready for the next discharge, or run. Any air entering with the liquid or steam is vented from time to time through X. The connection M can of course be dis- 7 connected from the lever and other connections, and the water drawn off by hand durin each run or at any convenient perio s.

The vent X can be replaced by a combined air and steam exhaust pipe Z connected with thesteam' supply by means of a three way cock, as shown in Fig. 2; thus, when the steam is cut oif, in conjunction with the V other operations already described, the cylinder is simultaneously opened to the atmosphere through the exhaust pipe Z, permitting its steam and occluded air to escape. The three-way cock is placed at a level higher than is likely to be attained by the liquid entering through H. With this arrangement the oil inlet H and outlet G can also be combined in one connection with a three way cock (as shown in Fig. 2) or the inlet H can be automaticallycontrolled by anon-return valve, opening to admit the liquid, but shutting against the steam pressure in the cylinder; and there may be provided in this arrangement also a scale or test pipe, andan outlet for water or condensation having its valve connected to the operating rod T as in the construction shown in Fig. 1.
